About Us

The history of California has a long and varied one with respect to the number of earthquakes that this American state has suffered. The occurrences can be traced to events like the California Gold Rush that occurred in the 1840s while other records of earthquakes can be found from the logs of explorers and ship captains. The earliest recorded earthquake in the region can be found from the logs of Spanish explorers who came to the region in 1769.

There have been earthquakes that damaged life and property in the East Coast as well as in American Midwest, which made the hazard apparent to the settlers in these regions. There have been shocks that affected populous areas like San Juan Capistrano in 1812, the Lone Pine episodes that occurred in 1872 or the Fort Tejon episode that occurred in 1857. The one that occurred in 1868 affected the financial hub located in San Francisco Bay Area. The episode that occurred in 1906 in the same area led to the government, realizing the gravity of the problem. Hence, more efforts were put into research on earthquake activities in this region. Since the early part of the twentieth century, trained geologists have been assigned to map the events and predict possibilities of earthquakes in these areas. The first monitoring earthquake program of the state was started by the University of California in 1910.

Today the rate of earthquake occurrences has not gone down, but they are regularly monitored and you will find the latest data on different portals. The blog topics here are related to the seismological activities in this area and effects of the same.
